Application filed May 9, 1913. Serial No. 766,546.

Taall who-m it may concern:

Be it known that I, ULrssns G. RocERs, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Retainers for Ball Bearings, of which the following is a specification.

My invention relates in general to ball bearings, and more particularly to an improved retainer and spacer for the balls,

and to an improved method of assembling the balls and retainer ring with the bearing rings.

The primary object of my invention is to provide a retainer ring for the balls of a ball bearing which will space the balls within, and permit them to freely rotate in, the.

practical form, and in which Figure 1 is ah elevational view showing my improved retainer ring in operative relation to the balls interposed between the bearing rings. Fig. 21s a cross sectional view, taken on the line 2-42 of Fig. 1. Fig. 3 is an elevational view of a portion of the retainer ring with the balls seated therein, before the keeper lugs have been bent around the balls; and Fig. l is a view similar to Fig. 3 in which the keeper lugs of the retainer ring have been bent around the balls seated in the adjacent recesses.

The same reference characters are used to designate the same parts in the several figures of the drawing.

Reference characters A and B designate the outer and inner bearing rings, between which the balls are interposed. The bearing rings are provided with circular shallow grooves a, b, which form a raceway between .the inner surface of the outer bearing ring A and the outer surface of the inner bearing ring B in which the balls are located.

a' and b designate the usual feed grooves extendlng laterally from I the circular grooves a and 6, respectively, through which the balls are inserted into the raceway between thebearing rings.

Y'My improved retainer ring is formed in single piece, preferably of suitable cast metal, such, for instance, as brass, bronze, or the like. The main portion of the retaining mug is sinuous, so as to form curved recesses opening alternately at opposite sides of the ring.

rt and (1 indicate curved seats to receive balls of and 0 such recesses opening towarone side of the retainer ring, while intermediate of such recesses are formed other recesses, such as 01 which open to the opposite side of the retainer ring and in which are seated, the intermediate balls 0 Adjacent oneside of each of the recesses in the retainer ring 1 is a laterally projecting lug cast integral with the ring and adapted go be bent around the ball inserted in'tliea jacent recess. 6 and e? designate such later; ally projecting lugs extending to one side of the retainer ring and ad'ac n't the recesses d and d and adapted to e ent around the balls 0 and 0 located insuch recesses, in the manner shown in Fig. 4.. c designates a similar laterally projecting lug extending to the opposite side of the retain erri'rig adja cent the recess d therein and adapted to be bent around the ball 0 inserted in such recess.

It will be understood that the preferred embodiment of myinvention illustrated in the drawing alternate recesses the retainer ring open to one side thereof, while the intermediate recesses opento the opposite side of the ring, and that the laterally projecting lugs are arranged alternately on opposite sides of the ring, one of such lugs being located adjacent one side of each recess.

In assembling my improved retainer ring with the balls so as to space them between the inner and outer bearing rings, I first insert through the feed grooves a and 22" into the raceway, formed by the opposing circular grooves a and b, a number of balls equal to the number of recesses opening at one side of the retainer ring. I then place the retainer ring between the bearing rings with the recesses opening at one side thereof around the balls which have already been inserted into the raceway. I then rotate t0 the outer rings untiF'tbe first 1 9f retainer ring as a and b, rough the feed grooves 11 F "taxing re; 12 e rename!
